Control of broadband acoustic radiation from structures using a piezoelectric double-amplifier active-skin
(Virginia Tech, 1997-07-23)
In this work, the potential of an active-skin is demonstrated for the reduction of broadband acoustic radiation from a vibrating structure. A simplified representation of the active-skin, employing acoustic monopoles as ...
Active structural acoustic control of aircraft interior flow noise via the use of active trim panels
(Virginia Tech, 1996-02-05)
<p>Modem jet aircraft interior noise can be categorized into two main types: tonal noise caused by engine imbalance or blade passage, and mid frequency broadband noise resulting from turbulent flow. This project addresses ...
Hybrid adaptive feedforward control of structures to seismic inputs
(Virginia Tech, 1996)
The key conclusions of this research are: 1. The EFXLMS algorithm demonstrated superior performance than the FXLMS algorithm during fast adaptive processes, in particular for non-stationary inputs. 2. Good attenuation ...
Adaptive tuned vibration absorber
